The Channel Master television antenna booster (preamplifier) will amplify digital and HD signals received by your antenna. This antenna amplifier is a high gain, low noise preamplifier used for weak signal areas to allow a weak signal that is present at the antenna to be amplified to a viewable strength. This TV antenna preamplifier works best for persons in weak signal areas and is subject to overdrive if used in areas with fairly strong signals. In stronger signal areas our medium gain preamplifier, the CM 7778 is a better choice.
The TV Antenna preamplifier is useful for persons unable to view channels due to weak signal. The preamplifier will boost the signal received by the antenna making it much stronger by the time it reaches your TV set.
The Channel Master preamplifier is a two part unit, an outdoor amplification unit which is mounted on the mast of your antenna system and an indoor unit which powers the outdoor amplification unit. The indoor unit is stationed indoors and connects to the outdoor unit via coaxial cable.
If you already have an antenna set up and are considering adding a preamplifier to boost your signal strength. You would only need two additional short length coaxial runs, one from the antenna output to the preamplifier input (which should be no more than 5 feet) and one from the indoor power-supply to your TV set. You would simply use the current longer coaxial run to connect from the mast mounted units output to the indoor units input.
